Displaying Database values in HTML - php

Question

I am trying to get the values from table and display the values in the html code.
I am working in 3 separate php files.
This is the Article.php file, which contains the Article class:
public static function getInfobar() {
$conn = new PDO( DB_DSN, DB_USERNAME, DB_PASSWORD ); //connecting to the db, the values are stored in config.php
$sql = "SELECT 'title', 'subtitle', 'additional' FROM infobar WHERE id=1";
$st = $conn->prepare ( $sql );
$st->execute();
$list = array();
while ( $row = $st->fetch() ) { //storing the info inside the array.
$infob = new Article( $row );
$list[] = $infob;
}
$conn = null;
return ( array ( "results2" => $list));
}
After I pull these values from database, I'm trying to display them in the HTML. Firstly I declare a function inside the front-end handler: index.php
EDIT: the method is being called by using the switch.
switch ( $action )
{
default:
homepage();
}
function homepage() {
$results = array();
$results2 = array();
$data = Article::getList( HOMEPAGE_NUM_ARTICLES );
$data2 = Article::getInfobar();
$results['articles'] = $data['results'];
$results['totalRows'] = $data['totalRows'];
$results['pageTitle'] = "TITLE";
$results2['info'] = $data2['results2'];
require( TEMPLATE_PATH . "/homepage.php" );
}
After, I am trying to display the values in the webpage like this:
<div class="row_item1">
<?php foreach ( $results2['info'] as $infob ) { ?>
<h1><?php echo htmlspecialchars($infob->title)?></h1>
<p><?php echo htmlspecialchars($infob->subtitle)?></p>
<p><?php echo htmlspecialchars($infob->additional)?></p>
<?php } ?>
<img src="" alt="">
</div>
But all I get is this:
I am kinda stuck here, trying to figure out what's wrong with the code for quite awhile now. Please help me out on this one. Much appreciated.

Change your query
$sql = "SELECT 'title', 'subtitle', 'additional' FROM infobar WHERE id=1";
to
$sql = "SELECT title, subtitle, additional FROM infobar WHERE id=1";
For User Requirement.
I'm not sure. But, it can be like this way. Since, i don't know the flow, i can suggest you to try like this way once.
public static function getFullInfobar() {
.
.
$sql = "SELECT title, subtitle, additional FROM infobar";
.
.
}
$results3 = array();
$data3 = Article::getFullInfobar();
$results3['info'] = $data3['results3'];
<?php foreach ( $results3['info'] as $infob ) { ?>
<div class="row_item1">
<h1><?php echo htmlspecialchars($infob->title)?></h1>
<p><?php echo htmlspecialchars($infob->subtitle)?></p>
<p><?php echo htmlspecialchars($infob->additional)?></p>
<img src="" alt="">
</div>
<?php } ?>
